Abstract
The utility model relates to a feeding device that supplies wet process ball mill to use, inside its gyration feed cylinder, arranged the lifting blade that the polylith was arranged according to certain angle slope all around along the guide cone, strengthened the carrying capacity of material. A section of spiral pipe is arranged at a feed inlet of the grinding machine, and the leaked materials can be timely sent back to the grinding machine, so that the leakage is effectively prevented. In addition, measures for reducing material scouring are taken on the inner wall of the rotary feeding cylinder, so that the service life of the feeding device can be prolonged. The device overcomes a series of defects of insufficient conveying capacity, poor sealing and the like of the existing feeding device. After the wet ball mill uses the device, the production efficiency can be improved, the resource waste can be reduced, and the clean production is realized.
Description
Technical field
The utility model relates to a kind of feeding bin device for the ball mill by wet process use, and this device mainly is applicable to metallurgical grinding industry and the central used ball mill by wet process of flue gas desulphurization environment-friendly engineering.
Background technology
The drawing-in device effect of ball mill by wet process is slip to be sent into carry out grinding operation in the grinding mill barrel.Slip generally adds water by solid material by a certain percentage outside mill formulated, has bigger flowability usually.Bucket wheel formula drawing-in device is arranged in early days, and bucket wheel turns round with ball mill, and the grinding machine revolution moves a week, and bucket wheel digs material once toward kiln basin.Its shortcoming at first is that the slip conveying is discontinuous, and conveying capacity also is restricted; Next is to cause on-the-spot slip to splash, and trickling everywhere, has both caused the material waste, is unfavorable for that again factory realizes cleaner production.Owing to have above-mentioned deficiency, adopt the ball mill of bucket wheel formula drawing-in device fewer and feweri.Uses at present the more elephant trunk formula drawing-in device that be, this apparatus structure is simple relatively, and material directly feeds quill shaft inside feed pipe by the elephant trunk of inclination, enters ball mill through feed pipe.But owing to be subjected to the restriction of quill shaft diameter, elephant trunk and feed pipe effective drift diameter are less usually, therefore cause the conveying capacity deficiency, influence ball mill and improve output.Particularly along with the appearance of cyclone, the slurry circulation amount increases exponentially, the corresponding increase feeding of an urgent demand ability, and elephant trunk formula drawing-in device is also just more difficult to satisfy the ball mill production requirement, often causes the charging aperture place seriously to leak.Leak for reducing,,, seal and be difficult to prove effective, caused unnecessary resources loss and environmental pollution because this position is in rotary state for a long time though having taked of having utilized the fixedly seal approach of rubber slab or wool felt of trim ring.
Summary of the invention
The purpose of this utility model provides a kind of new drawing-in device, and it not only can improve the slip conveying capacity, can also avoid slip to leak.After adopting this form drawing-in device, both created condition, and can reach again and cut the waste, prevented the purpose that production on-site environment is polluted for grinding machine volume increase.
The purpose of this utility model is achieved in that at one section with the simplified two ends of the rotating drum type of ball mill, be respectively equipped with charging aperture and discharging opening, in cylindrical shell, be provided with a guide cone by discharging oral-lateral center, guide cone center line is consistent with the cylindrical shell center line, and the small end of guide cone is towards the discharging opening direction.Along the guide cone some lifting blades that circumferentially distributed, guide cone and cylindrical shell are coupled together by lifting blade.These lifting blades are similar to the structure of screw, press the certain angle oblique arrangement, and the definite of incline direction is principle by charging aperture to the discharging opening motion to guarantee that cylindrical shell can promote slip when rotating.Be provided with one section spiral pipe in the charging aperture inboard, tube wall is furnished with helical blade, and the hand of spiral determines that principle is the same.The charging elephant trunk stretches into the drum type cylindrical shell by spiral pipe, and the slit between the body end surface adopt trim ring fixedly the mode of rubber or wool felt eliminate.Circumferentially be provided with the small gusset of some projectioies on the inwall edge of drum type cylindrical shell, gusset direction or a tilt low-angle consistent with tubular axis, incline direction is identical with lifting blade.
After adopting technique scheme, the lifting blade that is similar to propeller arrangement in the cydariform cylindrical shell can force slip along guide cone feeding ball mill, thereby improves the conveying capacity of slip, for the ball mill volume increase creates conditions.The spiral pipe that the charging aperture inboard is set up can in time be sent the slip that leaks back to the cydariform cylindrical shell, even also have a little slip to trickle outward once in a while, also can be stopped by outside trim ring fixing rubber slab or wool felt, avoid the slip waste thereby reach, prevent the purpose that production on-site environment is polluted.Simultaneously because the inwall of drum type cylindrical shell along the small gusset that circumferentially has additional some projectioies, cuts off and stoped the slip hoop to flow, effectively alleviated slip to the washing away and abrasive action of cylindrical shell, prolong cylindrical shell service life thereby reach, reduce the purpose of the wasting of resources.

Fig. 1 is the schematic diagram of an embodiment of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1. 2. lifting blade 3. guide cones 4. small gussets 5. charging elephant trunks 6. trim rings 7. rubber slabs 8. spiral pipe 9. cydariform cylindrical shells (II) of cydariform cylindrical shell (I)
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In Fig. 1, embodiment shown in Figure 2, the cydariform cylindrical shell is assembled by bolt by cydariform cylindrical shell (I) 1 and cydariform cylindrical shell (II) 9, guide cone 3 is radially evenly welded and has been arranged 12 inclination lifting blades 2, and lifting blade 2 also takes welding manner to be connected with cydariform cylindrical shell (I) 1.Cydariform cylindrical shell (II) 9 charging aperture inboards are welded with spiral pipe 8, and rubber slab 7 is fixed by trim ring 6 by outer face place, and the charging elephant trunk 5 that will stretch into cydariform cylindrical shell (II) 9 is waled.Cydariform cylindrical shell (II) 9 inwalls are welded with some small gussets 4.
Present embodiment is except that rubber slab 7, and remaining parts adopts metal materials such as steel plate.
